The 193 heads aren't the hot tip, thats for sure, but they'll work.
You should be able to bolt it together and be fine. Just use the standard cheapy fel pro gasket set or whatever set of head gaskets you can get cheaper. The 193's have a decent combustion chamber shape. Slap it together, test drive it, if you hear detonation back off 2 degrees, retest drive and listen again. If it still pings back off another 2 degrees, repeat until ping is gone.
